The lawsuit alleges that poker pro Phillip "Phil" Ivey Jr. allegedly cheated while playing several sessions at a Baccarat table in 2012, the report said.

While playing, Ivey allegedly cheated by fixating on pattern flaws on the back of the cards, a technique commonly known as "edge sorting," according to the lawsuit.

The lawsuit also names card manufacturer Gemaco Inc. of Blue Springs, Mo., who designed the cards, the report said. Also named in the lawsuit is a female partner of Ivey's, Cheng Yin Sun, who allegedly gave instructions to the dealer.

Ivey admitted to using a similar technique in a London casino in 2012, the report said. He won a 7.3 million pounds, or roughly $12 million, in one session. Ivey sued the casino last July when it refused to pay him.

Born in California but moved to New Jersey at a young age, Ivey mastered his craft by playing poker in Atlantic City throughout his teenage years with a fake ID, he said on his website. He has nine WSOP bracelets but has yet to win a Main Event championship bracelet, though he has made it to the final table nine times.
